## Reflection: More Solving Problems with Equations - Section 1: Warm Up

I want to ensure that my students have the ability to view a problem from different perspectives. This warm up allowed students to do that by viewing another student's setup for a word problem. Here are some examples of student work on the Warm Up: Word Problem Equations 2_SW

I was pleased with each student's explanation for the first question.  All students were able to say that both representations were correct because the distance between the numbers is five.  In the second question, the third student had a nice explanation. She substituted in two different numbers to show that you cannot tell whether "x" or "27-x" is larger.  Under the common core, we want students to have this habit of "playing with mathematics" in order to help make sense.  Once students can test to ensure something works in a concrete way they can generalize to a more abstract case.

Overall, this was a great opportunity to allow students to become comfortable with expressions and their meanings.
